GEORGE G. SCHROEDER, OF WASHINGTON, DISTRICT OF COLUMBIA, ASSIGNOR TO INDUSTRIAL ALCOHOL HEAT AND LIGHT COMPANY, A CORPORATION OF SOUTH DAKOTA.

DENATURED-ALCOHOL GAS-LAMP.

Specification of Letters Patent. l

Patented July 23, 1907.

To all 'whom 'it may concern:

Be it known that I, GEORGE G. SCHROEDER, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Denatured-Alcohol Gas-Lamps,

'of which the following is a specification.

This invention has relation to denatured aclohol gas lamps, and it consists in the novel construction and arrangement oi its parts as hereinafter shown and described.

The object of the invention is to provide a lamp of the character indicated which is adapted to convert liquid alcohol into a gas and mix the gas with air and burn the resultant mixture as an illuminant.

The parts are so arranged that the process above indicated is automatically accomplished.

The lamp consists primarily of a `font adapted to hold the liquid alcohol. A burner is mounted upon the font and is provided with a depending tube which projects well into the font. The lower portion of said tube contains a wick or other capillary agent. A starting burner' is arranged about the said tube at a point intermediate the ends thereof, and the said tube is provided with perforations which communicate with said starting burner. The said starting burner contains a fibrous material, and is coveredbya perforated plate with a rotatable perforated damper located above the same, and which is adapted to be moved so as to close the perforations of the said plate. The upper end ofthe said tube is provided with air admission ports. A perforated cylinder is located in the said tube, and is embedded in the upper end of the capillary agent. A volute tube is attached at its lower end to the said cylinder, and passes through the side ofthe first said tube, above the starting burner, then passes around the first said tube and connects at its upper end with a valve casing which extends radially into the rst said tube below the air admission ports thereof. Said valve casing is provided with a needle valve and a gas exit. The said gas exit being located concentrically with relation to the rst said tube. An incandescent gas mantle is arranged above the upper end of the rst said tube, and serves as the illuminant retaining medium.

In the accompanying drawingsz-Figure 1, is a perspective view of the lamp. Fig. 2, is a vertical sectional view of the upper portion of the lamp. Fig. 3, is a perspective view of the tube. Fig. 4, is a perspective View of the starting burner. Fig. 5, is a perspective view of the damper for the starting burner. Fig. 6, is a perspective view of the tube cap. Fig. 7, is a transverse sectional view of the tube showing the volute tube in position thereon. Fig. 8, isa perspective view of p starting burner above described.

The lamp comprises the font l, into the top of which is screwed the perforated gasket 2. The tube 3, passes through the perforation of the gasket 2, and extends well into the body of the font 1. The wick or other capillary agent 4, is located in the tube 3, and is prevented from entering the upper end thereof by the plate 5. The pan 6, surrounds the-intermediate portion of the tube 3, and rests upon the upper edge of the gasket 2. Said pan constitutes a startingburner. The tube 3, is provided with the perforations 7, 7, which communicate with the interior of the pan 6. The top of the pan 6 is covered by a perforated plate 8, and the perforated damper 9, is located over the said plate and is arranged to rotate about the tube 3. Said damper is provided with the radially extending handle 10, by means of which the said damper may be turned in order to bring its perforations in alinement with the perforations of the plate 8, or its closed portions over the same.

The cylinder ll, passes through the plate 5, and is concentrically arranged with relation to the tube 3, said cylinder is open at its lower end and is provided in its side with a number of elongated perforations l2, 12, which are vertically disposed. The said cylinderpis embedded in the capillary agent 4. The volute tube 13, attaches at its lower end to the upper end of the Acylinder ll, then passes laterally through the side of the tube 3, and spirally around the same over the The upper end of the tube 13, connects with the valve casing 14, which extends radially into the tube 3, and is provided with the gas exit 15, which is concentrically positioned with relation to the tube-3. The needle valve 16, is located in the casing 14, and is adapted to open or close the gas exit 15 thereof.' The upper portion of the tube 3, constitutes a mixing chamber, and is provided with a number of air admission ports 17. The mantle 18 is located over the upper end of the tube 3, and is incased within the chimney 19. If desired the upper end of the tube 3, may be covered by a screen 2l. y

The operation of the burner is as ollows:-The font l, is filled with denatured alcohol. This liquid is taken up by capillary attraction by the wick 4, and is carried into the brous material (such as asbestos) 20, with which the pan 6, is filled. The damper 9,-

is then turned so that the perforations of the plate 8 are open. A match is then applied over the said perorations and the fumes of alcohol within the librous material 20, are ignited. The resultant flame envelops the upper portion of the tube 3, and also the volute tube 13. The se parts become thoroughly heated, and the fumes of alcohol within the volute tube 13 are gasied. FWhen the parts are sufficiently heated, the needle valve 16 is opened and the gas escapes through the exit 15, mixes withair which enters the upper portion of the tube 3, through the ports 17, andthe resultant mixture is ignited and illuminates the mantle 18. The damper 9,' is then closed over the openings oi the plate 8, and the l'ame'irom the starting burner is doused. The liquid from the font 1, then passes up through-the Wick 4, and enters the cylinder 1l, in the form of a vapor. This vapor passes up through the volute tube 13, and is gasiiied by coming in contact with the heated sides thereof, and the gas thus formed passes out through the exit 15, of the valve casing 14, and is mixed with air and ignited as above described. 1norder to extinguish the light it is necessary to close they needle valve 16, only. Thus it will be seen that a simple and effective means for converting denatured alcohol intoan illuminantis provided, and that the parts may be readily operated in 4starting and extinguishing, and are unattended by dangerous elements.
